Patented June 9, 1953 UNITED STATES PATENT OFFICE TRACTOR-MOUN TED FERTILIZING IMPLEMENT 1 Claim.

This invention relates to novel and useful improvements in farm implements of the type which is adapted to be drawn by a tractor.

An object of thi invention is to open a furrow, deposit and mix fertilizer in the furrow and the soil forming the furrow and then deposit one or more grains of seed in the furrow, the placingof the grain or seed being accomplished in response to forward movement of the two connected frames on which the various appurtenances are located.

Another object of this invention is to vibrate a fertilizer hopper or at least a part of the fertilizer hopper, as for example, the bottom thereof, in response to the forward movement of the frame, this vibration or shaking causing a quantity of fertilizer to fall within a chute and since the lower end of the chute is located between the plow for initially cutting the furrow and a furrow side breaker mechanism, the fertilizer is deposited and then worked in the furrow soil.

Ancillary objects and features will become apparent in following the description of the illustrated form of the invention.

In the drawings:

Figure l is an elevational view of the device showing it attached to a part of a tractor;

Figure 2 is a top view of the mechanism in Figure 1, the tractor being omitted;

Figure 3 is an enlarged sectional view of a portion of the structure shown in Figure l, the tractor being omitted;

Figure 4 is a sectional view taken substantially on the line 4-4 of Figure l and in the direction of the arrows;

Figure 5 is a side view of a portion of the mechanism;

Figure 6 is a sectional view taken on the line 66 of Figure l; and

Figure 7 is a view taken on the line l! of Figure 1 and in the direction of the arrows.

In the illustrations there is a fragmentary portion of a tractor generally indicated at [0 and having various elements which are conventional, as a draw bar [2 with lift arms 14 connected therewith and also adjusting mechanisms I6 for the lower draw bar arms.

A first frame generally indicated at I8 is secured to the draw bar 12 and a second frame 20 is secured to the first frame by mean of a hitch 22. This second frame has a plate 24 secured to the forward end thereof (Figure 4) and said frame I8 has a yoke 26 at the rear end thereof (Figure 1) with a vertical coupling pin 28 passed through-the yoke and one of the number of aper- 2 tures in the plate 24. This forms a flexible bite for connecting the front or first frame with the second or rear frame 20 so that said frames I8, 20 are relatively swingable about a vertical axis.

The first frame includes the plow beam 30 which is secured at one end to the vertically rising arms 32 and 34, these arms being disposed on the tractor draw bar [2. The lower end of the plow beam carries the plow 36 which is adapted to cut a furrow as the tractor moves forwardly through a field.

A bearing plate 38 is secured to the draw bar and has the rearwardly diverging arms 40 and 42 secured thereto. These arms are also fixed intermediate their ends, to the apertured plate 44, which forms the rear part of the first frame [8. Secured to the draw bar 12 and forming a part of the front frame 18 is a pair of rearwardly converging arms 46 and 4B. These rearwardly converging arms are secured to the depending brackets 58 which are fixed rigid with the plate 44. Links 52 and 54 are secured to the vertically rising members 32 and 34 and to the brackets 50 at their junctions with the rearwardly converging arms 46 and 48.

By the above described structure, the entire front frame is capable of being lifted as the tractor draw bar is raised by means of the motive force mechanism normally connected with a tractor draw bar.

Disposed at the lower end of each rearwardly diverging arms 40 and 42, respectively, is a device for breaking the sides or, the soil forming the sides of the furrow which is opened by the plow 36. The devices 58 and 58 are identical in structure. The device 56 includes a bearing 60 of the split type with a chisel 62 passed thereth-rough. Inasmuch as the bearing is of the split type, loosening or tightening of the fastening screw allows the chisel to be adjusted therein. A flange 64 extends from one side of the bearing 60 and has a slot 66 therein. A screw 68 with an appropriate nut is passed through the slot and also through an opening in the arms 40. The lower end of the flange 64 is pivoted, as by the pin 10 to the lower end of the arm 48. Accordingly, pivotal movement of the bearing and the flange 64 about the pin H3 is permitted and when this pivotal adjustment is arrived at, it may be maintained by tightening the nut on the bolt 63.

A chute 12 having an inlet funnel i3 is bolted to a small plate i9 (Figure l) carried by the links 52 and 54. The chute i2 is adapted to receive fertilizer from the fertilizer box 80.

'Ihefertilizer box 88 is carried on a structural framing which forms a support 82 at the forward end of the second frame 20. The bottom 84 is mounted for reciprocation on the pair of rails or tracks 85 which are disposed at the lower open end of the hopper 80. The fertilizer box 80 is positioned over the hitch 22 to feed into said inlet funnel to feed into the chute 12.

Means for reciprocating the bottom 84 of the hopper is operatively connected with a packing wheel 88 which i carried at the rear end of the frame 20. This means consists of a shaft 88 which is mounted in suitable bearings on the frame 20 and which has a wheel 89 at one end thereof. A gear 90 is fixed to the other end thereof and has a chain 92 entrained therearound. This chain is also entrained around an idle 84, a sprocket 96 which is fixed to the packing wheel 86 and another sprocket 98 which is secured to a shaft I00. The shaft I is mounted in suitable bearings and also carried by the second frame.

The wheel 89 is provided with a plurality of pins I02 (Figure which strike an arm I04 which is pivoted to the support 82 (Figure 5). This arm is pivoted by means of a small shaft I06, which shaft has a plate I08 secured thereto. Plate I08 has a slightly curved slot IIO therein and a pin I I2 which is secured to one side of the bottom 84 of the hopper after passing through a slot H4 in one of the rails 85 for supporting the bottom, is

shaft I00 to oscillate, hence imparting a shaking or vibratory movement to the bottom 84 of the hopper 30. This causes the fertilizer to be dropped in the chute 12 for deposit in the furrow which has been opened by the plow 88. Thereafter, the devices 56 and 58 work the sides of the furrow with the fertilizer therein.

A pair .of links H5 and IIS are pivoted to and depend from the platform I I8, forming a part of the frame 20. At the lower ends of these links there is a pair of parting disks H8 for parting the soil very slightly in advance of the tube I20. Slots I2I and I22 are formed longitudinally in the links II5 and H6 intermediate their ends to accommodate bolts I2I', I22 which are passed therethrough. These bolts I2I, I22 also pass through links I24 and I26 which are pivoted at their upper ends to the platform H8 to incline rearwardly and downwardly across the links I I5, 5 and which have the packing wheel axle carried thereby at the other ends. Thus the links H5 and IE4, and IIS and I26 are interconnected respectively, by bolt and slot connections, for relative vertical adjustment of the parting disks H8 and packer wheel 88. The idler sprocket bracket I28 is also carried by the links H5 and H8.

A packing wheel cleaner I30 is mounted on a yoke 132 which is secured to the lower ends of the links I24 and I20. A slot is provided in each side of the yoke I32 to accommodate a pin. Each pin is passed through a spring-type drag member I34 and I38 (Figure 2) which is adapted to pull loose soil over the packed furrow after it has been operated on by the packing wheel 06.

VA grain or seed box I40 is disposed on brackets I42 which are carried by the platform I I8. This grain or seed box has a rotary distributor I44 (Figure .3) in the bottom thereof. The distributor is of the apertured plate type, which apertures align with a discharge opening I46 during operation thereof. Said tube I20 has a branch I48 extending therefrom which communicates with the discharge opening I46.

As the shaft 88 is rotated, the gear I 50 which is secured thereto and which is enmeshed with the gear I52 causes the plate I44 to rotate, since it is secured by means of the axle I54 and nut I56. Accordingly, in response to forward movement of the frames, the rotary distributor is operated through the chain and sprocket drive. A bracket I58 is secured to the grain box I40 and supports the upper end of the tube I28. It also supports a second grain box I60 which has an opening IE2 at the top part thereof. A rotary distributor wheel I64 is mounted on an axle I66 in the second grain box I60 and has its rotation imparted thereto through the gears I68 and I10, respectively. The gear I68 is fixed to the axle I66, while the gear I10 is fixed to a shaft I00. Inasmuch as the shaft I08 has the sprocket 98 secured thereto which is chain operated, forward movement .of the frames causes operation of this distributor.

The grain box I00 has its longitudinal axis tilted at an angle with respect to the horizontal causing the grain to flow by gravity toward the rotating disk I64. This rotating disk has a number of pockets I12 formed therein which, when they are at the top of their travel, communicate with the conduit I14, which conduit communicates with the tube I20. This deposits grain or seed in the tube I28, it being possible to employ two different types of grain or seed in the two hoppers or a single type in each.

In operation the tractor is set in motion in a field. The plow 36 opens the furrow initially and inasmuch as the bottom 84 of the hopper is shaken by the described structure, fertilizer drops from the hopper into the chute 12 for deposit behind the plow 38 and in the furrow which is opened thereby.

The soil forming the sides of the furrow is worked by the devices 56 and 58 causing the fertilizer to be Worked therein. Then, mounted on the second frame, and following behind the first frame, is the parting disks I I8 which open a small minor furrow in the larger furrow so that the seed or grain which is carried by both of the seed boxes I40 and IE0 respectively, may be dropped therein.

Rearwardl-y of the parting disks is the packing wheel 86, whence the force for operation of the hopper bottom 84 and the two distributors is obtamed. The packing wheel also serves its purpose of packing the furrow, while the members I34 and I36 pull loose earth over the sides of the packed furrow.

Having described the invention, What is claimed as new is:

For use with a tractor, a fertilizing implement comprising a first frame carried b-ysaid tractor to travel therewith, a chute and a plow in front of said chute both carried by said first frame a hitch means in alignment with said chute and plow fixed to said first frame and extending rearwardly thereof, a second frame pivoted to said h tch means to swing about a vertical axis, a fertilizer hopper secured to said second frame and positioned over said hitch means, said hopper bemg provided with movable feed means, said feed means having a forwardly located discharge end positloned over said chute, and means for imparting movement to said feed means to discharge fertilizer into said chute for deposit in the furrow formed .by the plow including a ground engaging wheel mounted on said second frame in alignment with said chute and plow, said wheel serving to support said second frame and pack the deposited fertilizer.
